Melt pressure sensors series SPX - 2

SPX-2 Series

The SPX-2 series is an intelligent 4-20mA pressure sensor designed for use in hazardous areas and is available with various process and electrical connections. The SPX - 2 series is a robust welded construction. These amplified transmitters eliminate the need for external signal conditioning. All models can be directly connected to high-level distributed control systems, PLCs, computers and similar control systems. Optional thermocouples or RTD configurations are also available for simultaneous temperature and pressure monitoring at a single connection point.
